The liquid-crystal display has the low voltage, the low power loss characteristic, matches with the CMOS integrated circuit.

The characteristic curves of the waveguide loss versus the number of transpositions and crossing angle are drawn out, which conform to the expcted loss characteristics of crossed optical waveguide.

The calculation results have shown that when the angles of the center electrode and the grounds decrease, the effective index, the characteristic impedance, and the conductor loss all decrease.
